thanx Philippa, I occasionally use a polariser but not that often, ( we dont get too many days that its needed), I think because i "see" in mono when im shooting architecture i also "see" the sky in mono and try to wait for appropriate skies, and i wont deny now and again popping the odd sky in over the original! lol
not on this one however this was the sky that was there that day,

here is the colour to compare...........
